Overhaul Information
Note:
Exhaust gas contains toxicant, DO NOT keep the engine run for a long time in a closed
or
poorly ventilated place.
● Inspect ignition system in the order of the content in troubleshooting table
● Refer to (12-11) for ignition system diagram
● Ignition advancer is integrated in the CDI, so the ignition system will
automatically adjust ignition time.
● Be careful with CDI overhaul. Dropping or strong impact may cause damage to
CDI. In addition, over voltage may be generated on CDI and cause damage to
return circuit when removing or joining the connectors and terminals with switch
ON .Always shut the ignition switch when overhauling.
● Most of the failures of ignition system are caused by faulty contacts between
connectors and terminals. Check all the connections for any faults before
overhauling.
● Select spark plug of proper heat value. Improper spark plug may cause malfunction
or damage of engine.
● Refer to Chapter 13 for inspection of switches
